Abstract
An entropy source extracts noise associated with the sampling of an RC circuit. The decay time of the RC circuit and other parameters are selected so that a buffer used to sample the voltage remains in an indeterminate voltage region over multiple clock cycles to generate random transitions. The entropy source may be implemented to be compliant with government standards for entropy sources utilized to generate random numbers.
